CHIROPRACTIC TABLE.

To zzZZic/z 0m it may concern:

Be it known that I, CARL T. LINDHOLM, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented a new and useful Improvement in Chiropractic Tables, of which the following is a specification.

My invention relates to tables consisting of two members, each of which is composed of collapsible parts, capable of being folded, each member when folded fitting into the other in such way as to give the appearance of an ordinary suitcase and the object of my invention is not only to provide a table which may give the appearance of an ordiclosing the dorsal cushion of the head member.

Fig. 2 is a side elevation showing the suitcase member set up, ready for use.

Fig. 3 is a side elevation showing the head member set up, ready for use; disclosing the dorsal cushion.

F at is a bottom plan view of the suitcase member on edge opened and showing its parts unfolded. i i

Fig. 5 is a bottom plan view of the suit case member on edge opened andshowing its parts folded.

Fig. 6 is a bottom plan view of the head member on edge opened and showing its parts unfolded.

Fig. 7 is a bottom plan view of the head member on edge opened and showing its parts folded.

Similar reference characters refer to similar parts throughout the severalviews.

By comparison, Figs. 2, iand 5 will be understood to comprise a longitudinal section of a suitcase 1 designed to have two pairs of legmembers 2 and 2, arranged against and within its ends, secured therein by hinges 6.

Leg members 2 are united by brace board 2 in their top ends, which brace board. 2

has its ends cut diagonally, presenting a long Specification-of Letters Patent.

Application filed February 19, 1820. Serial No. 359,934.

and a short side, its long edge being dressed at an obtuse angle, fits flush with the top crosswise of thesuitca'se member 1, and is secured to the leg member 2 by ordinary screw means not shown, and is also intended to furnish a fiat bearing surface in and across the end of suitcase member 1, a further purpose of brace 2? being to add stability to the said legs and tables. The said leg member 2 being attached at either end of brace board 2 at an obtuse angle permitting them to spread laterally toward their bottom ends. and when folded fitting closely within the sides of suitcase member 1, each being secured by screw means, not shown, crosswise of the said brace board 2 beginning at the angle of the short side of brace board 2 and fold and unfold in said suitcase member 1 by means of the hinge attachments 6 attached to their ends. The brace board 2 is provided with the diagonal ends for the double purpose of causing the legs 2 to be set farther in from the sides of suitcase member 1 and to enable the pair of legs attached thereto when being folded and unfolded, to pass the corner braces 1 provided upon the adjacent cornersof the suitcase member 1. i

The pair of leg members 2 are provided at their top ends with a brace board 2 extending crosswise of suitcase member 1, said b ace board 2 having its ends cut diagonal and its top or short edge being dressed at an obtuse angle fitting flush with the top, crosswise of suitcase member 1, connecting said legs and secured thereon] by screw means, not shown, and likewise furnishing a fiat bearing surface in and across the end of suitcase member 1, the ends of said brace 2 being diagonal, enabling said legs 2% spread laterally and enabling them, secured by hinges (S at their tops, to fold and unfold in close proximity within and to the sides of the suitcase member 1, and to inclose between them when folded, the legs 2, a further purpose of said brace board 2 being to add strength and stability to the legs and. table.

Each pair of legs 2 and 2 are held in place when unfolded respectively by V- shaped metal braces 3 and 3 each having their wide ends bent angulate to form journals and having their respective apeXes bent both block letter style and laterally, their respective angulated journal ends being in serted into eye means 2 provided in the inner surface of legs 2 and 2 in such way that when the leg members 2 and 2 are folded the apeXes of the V-shaped metal braces move longitudinally from the center of suitcase member 1 and toward the ends thereof.

In the center of suitcase member 1, on its inner side 1 provide an oblong slat 4, having a pair of cross grooves 1 therein arranged at either side of its center, the slat 4 secured to the suitcase member 1, by ordinary screw means a, said grooves being made deep with perpendicular sides in order to retain therein the laterally bent ends of braces 3 and 3.

1 have also provided over the said oblong slat 1, a rotating hasp or button 5 loosely secured to said suitcase member 1 by means of bolt 5, the purpose of securing the braces 3 and 8 within the grooves 43 when the braces 3 and 3 by means of legs 2 and 2 are unfolded.

suitcase member 1 is in box form, having anopen side and is further provided at one of its ends on its open side adjacent to legs 2 mounted therein, with corner braces 1 of irregular quadrilateral dimensions conformableto the irregularly formed corners of the corresponding head member shown as Fig 6; the other end at its open side 21C jacent to legs 2 mounted therein, being pro vided with corner braces 1 of triangular dimensions conformable to the triangularly formed corners of the corresponding head member shown as l ig. 6, each of said corner braces being so formed ano. placed thereon forthe purpose of adding strength to the table and to cause, the same to fit suitably the form of the head member 8.

Theend of suitcase member 1, adjacent to brace 2 is centrally provided with an inside lateral roove 7, of oblong dimensions corresponding to the protruding tongue 1% of head member 8. The opposite end of said suitcase member 1 is provided with any ordinary fastening means, not shown, for engaging the corresponding fastening means provided in the corresponding end of the head member 8, thus with the tongue device 14 inserted in groove 7, to secure the said suitcase member 1 and head member 8 unto each other when said machine is folded together, as shown in Fig. 1.

head member 8, when the members 1 and 8 are folded and attached together, completing the suitcase form shown as Fig. 1.

The head member 8 is provided in either end with pairs of legs 9 9, each pair laterally spreading, and similar to legs 2 and 2 0f suitcase member 1, each pair of which are similarly connected with braces 9 and 9 as legs 2 and 2 are to braces 2 and 2, which braces 9 and 9 are respectively of similar construction to the braces 2 and 2 of suitcase member 1, each pair being at tached to such head member 8 by hinge means 13, as shown in Fig. 6, and so rendered capable of being folded and inclosed as legs 2 and 2, with reference to each other and also within said suitcase member 1.

Each brace 9 and 9, 2 and 2 is also centrally provided with notches 9 and 9, 2 and 2 on their top edges for the purpose of admitting the bent aperies 10 of the leg brace 10 and 10 and 3 and 3 of leg braces 3 and 3* when the legs are folded, thepairs 9 and 2 folding outside and clear of the pair 9 and 2 when the suitcase is folded as shown in Fig. 1, the pairs 9 and 2 resting upon each other and the pairs 9 and 2 resting upon each other.

Legs 9 and 9 of head member 8 are respectively provided with t-slraped metal braces 10 andlO of similar construction and serving similar purposes to the l-shaped metal braces 3 and 3 of suitcase member 1, for the like purpose of holding the legs in position when the head member 8 is set up and in use, which V-shaped metal brace is attached to said legs 9 and 9 at a similar place and by eyelets 9 at their journaled ends and when the legs 9 and 9 are unfolded, the block letter formed laterally bent apeXes 10 and 10 of said braces 10 and 10 are secured in grooves 11 of the oblong slat 11. The said oblong slat 11 being socured to said head member 8 by screw or other means 11 and when said brace ends 10 are inserted in said grooves 11", the same are held therein means of oblong rotatable turn button 12 which is centrally loosely secured upon said slat 11, by bolt or other means 12; the construction, operation and purpose of said parts being similar to said parts 4 and 5 of suitcase member 1.

It will be observed that head member 8 is slightly narrower than suitcase memb r 1, and made to fit within its sides, and has it respective corners 8 8 cut away; so formed for tile purpose'of eonformin to the human shape and to facilitate its adaptation to use by the operator, one of the ends called the blunt end havin its corners cut away in triangular form 8 so that slat 8 attached crosswise of the blunt end of head member 8 and triangular corners S may fit snugly within the corresponding reber 1.

8 is also provided with a slat 8 fitted crosswise of said end suited to fit in the recess 1 provided in the pointed end of suit case member 1, between the corresponding irregular quadrilateral corner braces 1 the use and purpose of slat 8 being similar to that of slat 8 at the blunt end, as stated. The corners 8 of head member 8 so cut away, are of irregular quadrilateral dimensions and so made to cause the same to fit connectedlywith slat 8 also attached to the pointed end of head member 8, in recess 1 snugly within the space between the corresponding irregular quadrilateral dimensioned corner braces 1 of suit case mem- Oblong slat 8 of said head member is also provided with a fastening device consisting of an angulated tongue 14 secured to said oblong slat 8 by screw means not shown, for the purpose of being fitted engagingly into the groove 7, inwardly provided in the end of suitcase member 1., when it is desired to fold and close the suitcase as shown in Fig. 1; said head member 8 and suitcase member 1, each being also out wardly provided at their opposite ends with ordinary latch members correspondingly attached, but not shown, for securing the one to the other when the said table is folded and put together as shown in Fig. 1.

It will be observed that when the parts designated as suitcase member 1 and head member'S are fitted and engaging-1y attached to each other with their various at-' tachments and working parts folded down, and pressed together, the curve of the spring braces 8 and 3 and 10 and 10: in connection with the legs unto which they are attached, pressing upon each other, form a cushion spring, preventing noise of the parts in handling and transportation.

It is further observed that in the formation of the head member 8 its sides are differently constructed in that, one of its sides has the leg attachments 9 and 9 while the opposite side is'constructed so as to form what is known as a dorsal'cushion 8 and is constructed by the top having its surface padded with padding increasing in thickness and rounded toward the end slat 8 and in such manner as to conform to the breast bone and tapering waist line of a human being when reclining face downward thereon, thus forming a dorsal cushion 8 for the purpose of protecting the sternum, breast and vital organs of a human body from jar and bruising when receiving a chiropractic adjustment, and to enable the operative chiropractic and osteo path to trace the nerves and massage the muscles over the front region of the body without interference from the table and to prevent bruising the body while the body remains in proper position for such treat--, ment; and to further facilitate this result, the legs 9 of head member 8 attached farthest from the thickestend of said padding are made suitably longer than legs 9 'of the same member'to elevate their end of the member 8 above its opposite end and legs 9 are caused to slant considerably outward toward table 1, which construction of legs 9 and 9 is for the further purpose of preventing the table 8 at the time of a chiropractic thrust from upsetting, slipping in any direction, tilting, jarring and to brace; the braces 10 and 10 attached thereto respectively being likewise alsovmade of suitable length to facilitate these results, that of the broad end 10 being made the longer.

In construction legs 9 with brace 10 of head member 8, and legs 2 and brace 3 of suitcase member 1 are of equal length and corresponding slant, making the corresponding ends of members 1 and 8 of equal height, while legs 2 and brace 3 of suitcase member 1 are suitably longer, but so at tached to the suitcase member 1 as to their greater slant and the angulating of the top edge of brace 2, to allow and cause the suitcase member 1 to set level in every direction when its legs are unfolded and it is set up, the purpose being by the slant of the legs of members 1 and S, to prevent any slipping or moving of the members 1 and 8, in operation.
